Abstract
The invention provides a linking electric explosion valve for a gas cylinder. The electric explosion valve comprises a valve body, an electric explosion tube, a piston, a crank, a rotating shaft, a pressure lever, a connecting plate, a pressure arm, an ejector rod, a spring, a safety diaphragm, a valve core, a needle valve core, a needle valve rod and a hand wheel. In a non-operation state, the electric explosion tube is not started and an arc-shaped surface in a groove of the rotating shaft is buckled with an arc-shaped gap in the pressure arm; in addition, the valve core plugs a through-flow port of the valve body; in an operation state, the electric explosion tube is driven to detonate and the piston is pushed to upwards move by the generated explosion pressure; the crank rotates for an angle by the piston rod; meanwhile, the crank is linked with the rotating shaft to rotate; when the arc-shaped surface in the groove of the rotating shaft is separated from the arc-shaped gap in the pressure arm, the pressure arm rotates around a connecting shaft and drives the pressure lever to move upwards; a pressing force on the valve core is released; at the same time, the valve core moves upwards under the actions of the air pressure in the gas cylinder and a spring force in a valve bush and compressed air in the air cylinder flows out through the through-flow port of the valve body. According to the linking electric explosion valve provided by the invention, the opening and the closing of the valve body can be realized safely and reliably through mechanical linkage.
